`Indalia omueo elplnhuli 1H y Willms 4P Il i 4 5 Wl TNESSES Ait PATENT Acniiiiiveniz' n. nnnnnasnorr, or Homann-NEW You ni-.nveriiqe-TRUCK To all whom t may concern Beit known that L'CHAUNGEY M. HEN- DERsHo'r'r, a citizen of the United States, and

a resident of the city of Hornell, -in the county of Steuben and State of, New York,

have invented anew and Improved Elevating-Truck, of which the following is a full,

clear, and exact-description. This invention relates to improvements in elevating trucks, an object of the invention being to provide a truck-with an improved mounting for a platform, and improved means'for elevating the same.

Ai further object is to provide a truclr of the' characterstated which of great simplicity, which can be easily operated, and which will be of maximum strength and durability. .l

A further ob'ect is to providea-truck in which the plat orm ma be given any elevation desired, and whic when elevated will securely support the load thereon. With these and other objects in" view, the v invention consists in certain novel features of construction vand combinations and arrangements of parts as will be' more fully hereinafter described and pointed out-in the claims.

In the accompanying drawm Figure l is a view in longitu al section illustrating theplatformv in elevated positioii.

Fig. 3 is a view in end elevation with the platform fully elevated.

1 represents a supporting frame, preferl ably of the general rectangular shape shown,

comprising side bars 2fand end bars 3 secured together in any approved manner.

The frame 1 is supported on wheels 4, the

,frontwheels connected by a turn table 5 with the frame and having a handle 6 to steerfithe truck as it is moved from place to place.

An adjusting rod 7 extends longitudinally of the frame 1, is mounted in bearings 8 in the ends 3 and provided with shoulders 9 to prevent longitudinal movement of the frame.

The rod is provided with right and left hand screwthreads 10 and 11 at opposite sides of its center,'and a crank arm 12 is secured on one end of the rod to turn 'the same. U

A set screw 13 is located in one end bar 3 and projects into a groove 14 in the rod and.'

'the direction 0f rotation of j Risers 20 are ,have their lower edges l and rest upon the side inner `faces of the sides 2, and

form and Fig. 2 is a view inside elevation showing the platform partially elevated.

assists in holding the rod against longitudinal movement.

l end with openings 16y receiving guide stand-` ards `17 fixed to frame 1 and having heads 18 at their up er ends limiting the upward vmovement oi the platform.

Internally screwthreaded sleeves- 19. are

mounted on the threaded portions 10v and 11 of the rod 7 and are caused to movetoward and away from'each other according to the rod.

connected by relatively wide hinges 21 with the sleeves 19 and these risers positioned to engage bars 2 o f the frame 1, and are made with the lugs 22 engaging the preventing possibility of lateral displacement. The risers 20v are preferably of skeleton may be constructed in any desired manner to give the necessary strength and rigidity with. the least- Their upperedges bear against the platform (orifice.

possible weight'.

15 throughout its width and give'the maxii mum support thereto. t

en the rod'7 lis tu'rned'in one direction it will cause the sleeves 19 tomove apart and through the medium of the risers 20 will elevate the platform 15. When the rod is turned in the opposite direction the platform will be lowered, and while of course lthe maximum of strength is hadiwhen the platformis in its extreme positions, it may be adjusted to any height desired two extremes of movement. A

Various-slight changesl might be made in the general form of the parts described with! out departing from my invention, and hence Il do not limit myself l.to the precise details set forth but consider myself at liberty to make such sli ht changes and alterations as fairly fall wit inthe spirit and scope of the appended claims.

claim:-

' LA truck of the character stated, comprising a wheeled frame, a rod supported longitudinally in the frame and having right and left screwthreads thereon, sleeves on the threaded portions of the rod, .a platform, and risers hingedly connected to the platform and sleeves, and having their lower edges projecting -across and supported on the frame when the platform is elevated.

2. A truck of the character stated, comwithin the prising a Wheeled frame, a rod supported longitudinally in the frame and having right and left hand screwthreads thereon, a platform, risers hingedly connected to the platform `and sleeves, said risers engaging the platform throughout its width and resting on said frame when the platform is elevated, and lugs on the risers engaging the inner faces of the frame.

10 3. A truck, comprising a wheeled frame,

standards on the frame, a platform alcove the frame and having openings therein receiving the standards, risers hingedly connected to the lower face 4of the platform, means movable longitudinally of the frame for moving the risers from an angular or horizontal position to a vertical position to elevate the platform, and said risers .at their outer ends suvported4 on theframe.
